Loading tweeter stats into WinISD

[Txgrizzly]

All,
i just downloaded WinISD from the web and i was able to load my Dayton RS150S-8 perameters no problem but the program wont allow me to load the Dayton RS28A-4 1-1/8" Aluminum Dome Tweeter due to missing parameters like QTS, VAS, LE ETC... is there a place where i can get those #'s for a tweeter or is there a way to get the tweeter loaded into WinISD without them?

Last time I checked WinISD like Unibox is only for designing boxes (midwoofers/woofer/subs) not speaker systems. So it doesn't know what to do with a tweeter

well D@#$ ok thanks Thomas, is there any shareware anywhere that can do it all or can you recomend a good program that i can buy from PE that will

1. help design cross over
2. help design enclosure
3. can show all the frequency responses for different drivers so i can see how the match up in a enclosure...

THanks
Bill

I would be curious in a Unibox like program that would show cone/dome excursion for a tweeter. I think it would be helpful in modeling high-pass filters. Anything out there for this?

I believe it would be more straightforward to use linkwitz's spl_max.xls spreadsheet which shows 2*pi max spl given surface area and stroke. If you are curious just to see a curve fit of an ideal transfer function relative to measured performance, ARTA will let you overlay some predefined functions, otherwise you could just graph a transfer function in excel using complex arithmetic.
